Description:

1.Brief introduction

Drill fluid used high temperature filtration SPHN which consists of nitro humic acid,sulphur methyl phenolic resin.SPNH contain multi active group to have multi-function and is one kind of high efficient fluid loss agent,and have visbreaking efficiency.because the SPNH resin molecule link draw resisted high temperature,resisted salted,obviously to increase the performance of resisted salted.that can be used in the deep well of the formation with high temperature,resisted temperature is 200°c obviously decrease the filter loss of the fresh water,salt water and saline mud.

2.Technical performance parameter

Appearance:dark-brown powder

Water content:≤10%;

API filter loss:4% fresh water liquid≤10ml;saline water liquid(NaCl)≤15ml;

HTHP filter loss:4% fresh water liquid ≤30ml; 15%saline water liquid (NaCl)≤35ml;

Apparent viscosity reduced rated:4% fresh water liquid ≥50%; 15% saline water liquid(NaCl)≥20%;

3.Usage and function

Drill fluid used resisted high temperature filtration SPNH is one kind of multi-purpose and multi-function drill fluid treating chemical

Available to different drill fluid system,have the obviously decrease fluid loss,and parts to make visbreaking

As mud thinner

Nonpoisonous,no environment pollution

4.Usage and amount

Directly enter into  the heavy copper,also match with collo fluid to adding.recommend adding amount 0.5~1%.

5.Package

Packed with triad-one composited knitting bag,each bag is 25kg net weight.
